ATTACHMENT FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 617,350, dated January10, 1899.

Application filed March 9 1898.

To all whom it may concern:

Be it known that I, THOMAS OLIVER, of Woodstock, in the county of Kaneand State of Illinois, have invented certain new and useful Improvementsin Attachments for Type- Writing Machines; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to a novel device for supportinga roll of paperupon a type-writer which is adapted to be fed to the machine as it isunwound from the roll, and refers more specifically to a device of thischaracter adapted to feed to the platen ofthe type-writing machine anarrow strip of paper which may or may not have been previously dividedby weakened lines into a plurality of short sections at any desiredpoint longitudinally of the platen.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 illustrates my novel device in verticalsectional view as attached to a type-writing machine, the parts of themachine shown being in transverse section. Fig. 2 is a plan sectiontaken on the line 2 2 of Fig. 1. Fig. 3 illustrates a roll of paper usedin the holder removed therefrom. Fig. 4: illustrates in perspective viewthe supporting-pin by means of which the roll of papeer is supported inthe device.

As shown in said drawings, A designates the platen of the machine, B B B'presser-rollers by which the paper is maintained in proper positionupon the platen, and O G designate the usual paper-guides, which "areattached to the machine in any preferred manner and by which the advanceedge of the paper is properly guided between the platen and the firstpresser-roller B. This particular type of machine has been shown for thepurpose of illustrating one practical adaptation of my device to atype-writing machine; but it will be understood that the same may beapplied to machines having a platen and presser-rollers otherwisearranged.

My novel roll-support consists, essentially, of a guide D, which whenupon the machine Serial No. 673,168- (No model.)

fits closely adjacent to the entrance between the roller-platen A andpresser-roller B and in position to accurately guide a strip of paperbetween the same. Said guide is provided with supporting-arms D, whichextend to the rear of the type-writing machine and support, preferablyabove the level of the machine, a roll of paper E, said supporting-armsbeing laterally separated and provided with a transverse supporting-pinD upon which the roll of paper E rests and turns as the paper is fedtherefrom. Said device is provided with a clamp D by means of which itmay be secured to a stationary part of the machinecarriage, and isprovided also with transverse brace-arms D D which are adapted to abutsquarely against a part upon said carriage which extends longitudinallyof the carriage and by means of which the device is prevented fromoscillatory movement with respect to the carriage, and the roll is heldwith its axis accurately parallel with the platen, so that it will runsmoothly from the roll to the platen.

The guide D is herein shown as of tubular form, consisting of connectedside, bottom, and top walls. The essential feature of such guide,however, is the side and bottom walls, by means of which the strip ofpaper carried upon the same will be directed in a straight line underthe platen transversely of the same. It is obvious,therefore,that exceptas a means for connecting the side walls of the guide the top wall maybe dispensed with and the bottom wall need not extend uninterruptedlyfrom one side wall to the other. Said guide D extends in a linetangential to the circumference of the platen A and lies closelyadjacent at its forward end to the lower part of said platen, so thatthe course of the paper from said guide to the roller will be nearly ina straight line. The supporting-arms D are herein shown as made integralwith the metal plates forming the sides of the guide D and forconvenience are made of circular form at their rear ends to approximatethe form and size of the rolls of paper to be used therein, so that theyform, in eifeot, a shield for the paper-roll as well as a supporttherefor. The

lower edges of said supporting-plates are secured together by means of acurved connecting-wall D which prevents the paper from to the lowerrearwardly-extending paperguide 0 of the type-writing machine, saidbottom wall of the guide resting on top of the paper-guide and the clampbeing provided with a clamping-screw (Z,which impinges upon the lowersurface of said paper-guide O, and thereby secures the device rigidly inplace upon said guide. In order to prevent the bottom wall of said guidefrom marring the upper surface of said paper-guide O, a cushioningpad d,of felt or the like, will be interposed between the proximate faces ofsaid parts. The strip of paper forming the roll E is of considerablyless wid th than the length of the platen-roller A, so that said devicemay be clamped opposite to any portion of the roller desired or foundmost convenient with reference to the mechanism of the particularmachine upon which the device is used. The stops which control themovement of the carriage will conveniently be set to correspond with theposition of the device upon the machine in a familiar manner. Byshifting the paper-holderlongitudinally of the platen c011- stant wearon one part of the said platen at one spot is prevented. As hereinshown, the transverse brace-arms D abut against the rear edge of theupper paper-guide O to prevent oscillatory or lateral movement of thepaper-supporting roll with respect to the paper-guide 0. As abovestated, however, said transverse brace-arms may coact with anylongitudinally-arranged portion of the machine-carriage for the purposedescribed. Said brace-arms are made to extend some distance beyond thesupporting-arms, so as to distribute the side strain of the device overa large portion of the guide C or other part and to thereby hold thedevice more rigidly upon the carriage.

In order to provide means for guiding the paper strip after it haspassed the platen and has received the impression of the type charactersthereon, a curved wall D is formed in the forward portion of the devicebetween the guide D and that portion of the supporting plate engaged bythe roll-supporting pin D The supporting-plates on either side of saidcurved upper wall D are extended a short distance beyond said wall toform guideflanges 61 which project at their lower ends over the upperpaper guide 0, as herein shown, or other equivalent part of the machinein the form of guide-prongs 61 The free end of the strip E after it hasreceived the impressions from the type characters will pass upwardlyover the guide-su rfaces formed by said curved wall D and flanges (1 Inorder to facilitate the feeding of the strip of paper E through theguide D in the first instance, said curved guide-wall D will be providedwith an oblong opening (1, through which a suitable instrument may beinserted to force through the guide the advance end of the strip.

As afurther and separate improvement and to provide means for detachablyholding the roll-supporting pin D in place upon the supporting-plates Dsaid plates are provided with opposite circular apertures, through whichthe pin D which is of cylindric form, passes, and across one of saidapertures is placed a locking-pin d, which is rigidly secured to theplate on opposite sides of said aperture by soldering or otherwise. Thesupporting-pin D will preferably be made of tubular construction and isprovided at diametrically opposite points in that end opposite its headwith slots d extending parallel with the central axis of the pin. Saidslots open at their inner ends into other slots al which extendcircumferentially of the pin and in opposite directions with relation toeach other. In order to lock the device, the pin is inserted into placewith the recess (Z engaging the locking-pin (1 after which the pin isrotated in the proper direction to carry the circumferential recesses dinto engagement with the pin. At this time that portion of the wall ofthe pin between said circumferential recesses and the outer end of thepin will prevent the same from being withdrawn endwise until it has beenrotated in a reverse direction to carry the recesses 61 opposite thelocking-pin.

The device herein illustrated and described may be used wherever it isdesired to print characters by the use of an ordinary typewritingmachine upon a relatively narrow strip of paper. Said device, as it iscapable of being adjusted or shifted to any convenient point along thelength of the carriage or platen thereof, may be adapted to any machinewithout any change in the organization thereof. The roll of paper shownin Fig. 3 is provided at regular points in the length thereof withweakened lines 6, at which point the sections bounded thereby areadapted to be torn from the strip and to be used in the form of smalltags for any purpose desired. Each of the sections of said strip areshown as provided with a perforation c, by which it may be convenientlysupported upon a filing-pin or the like after it has been printed uponby the machine and has been detached from the main body of the strip E.
